    "abstract": "A two-photon emission of a medium with periodically time-dependent refractive\nindex is considered. The emission results from the zero-point fluctuations of\nthe medium. Usually this emission is very weak. However, it can be strongly\nenhanced if the resonant condition $\\omega_0$ = 2.94 $c/l_0$ is fulfilled (here\n$\\omega_0$ and $l_0 $ are the frequency and the amplitude of the oscillations\nof the optical length of the medium, respectively). Besides, a medium with\nresonant oscillations of the optical length performs the phase conjugated\nreflection with high efficiency. A similar resonant enhancement of the\ntwo-quantum emission of other bosons is also predicted.",
